Signet – Open Source Password Manager

Signet is a compact, open hardware, and free and open source software USB device that safely stores your passwords, bookmarks, contacts, and other personal data in encrypted memory. It’s compatible with MacOS, Linux, Windows, and Android so you can use it on any device with a USB port. The device is smaller than the average house key, making it easy to take with you wherever you go. This makes Signet a practical alternative to storing sensitive data in the cloud. Unlike cloud-based or proprietary solutions, Signet is fully auditable with no proprietary software, firmware, or binary blobs to potentially hide security flaws.

A Powerful Cross-Platform Application

Access your data through a cross-platform application that unlocks your data with your master password. Once unlocked, Signet acts as both a password manager and a general personal information database. Signet acts as a USB keyboard to allow you to easily enter data into web forms. Signet can also type both a username and password to log you into a website instantly. The application features an intuitive graphical interface as well as keyboard based navigation to enable you to perform common tasks quickly.

Easily Access Your Data Anywhere

On desktop operating systems (Windows, GNU/Linux, MacOS), the Signet application software can run as a standalone executable with no driver installation needed, allowing you to quickly access your data at new locations. If you’re away from a computer, you can still access your data on your Android device through a USB host adapter cable.

Physical Security for Peace of Mind

Unlike pure software solutions, Signet protects your data from any hostile software on the systems you use. Signet will not transmit, modify, or destroy any data without the command being confirmed by a button press when the device flashes. This physically secures the device because only the user can press the device’s button. No system’s security is absolute, but physically requiring a button press to confirm sensitive operations increases the complexity and decreases the potential effectiveness of any attack.
